Recently it has been reported that differential speed rolling (DSR) is effective for improving tensile elongation and formability of magnesium alloys by reducing the intensity of basal texture. Thus, it is of great interest to coine TRC and DSR technique for more efficient production of magnesium alloy sheet with improved ductility.
Dynamic recrystallization (DRX) occurring in tensile deformation of AZ31B magnesium alloy sheet has been investigated. In particular, in order to predict the effect of DRX on tensile properties of AZ31B magnesium alloy sheet, a modified constitutive model is presented and used in the finite element method (FEM) model of the tension. Results from this analysis are compared with the experimental
Dec 23, 2019· As with all magnesium alloys, special precautions must be taken when machining Working with AZ91D Designers of structural components must be aware of the creep limitations of magnesium alloys—generally with increasing temperature, the tensile strength, yield strength, and hardness of magnesium alloys decreases, while ductility increases
The samples used for tensile tests were machined into various test piece sizes with the aid of lathe machine. The test piece was machined to comply with ASTM B557 (standard test methods for tension testing wrought and cast aluminum- and magnesium-alloy products). The test pieces were subjected to constant extension rate tensile test
Microstructure and mechanical properties of 6061-T6 aluminum alloy/304 stainless steel (Al/steel) joints welded by inertia friction (IFW) and continuous drive friction (CDFW) were studied comparatively. Morphology, microstructure, interfacial composition, and mechanical properties of Al/steel joints were investigated. Results showed that an intermetallic compound (IMC) reaction layer was
In this paper, studies were conducted to investigate the deformation behavior and microstructure change in a hot-rolled AZ31B magnesium alloy during a tensile-tensile cyclic loading. The relationship between ratcheting effect and microstructure change was discussed. The ratcheting effect in the material during current tensile-tensile fatigue loading exceeds the material’s fatigue limit and

Magnesium. The eighth most abundant element in the earth’s crust, and the fourth most common element in the earth overall, magnesium was discovered in 1775 by Sir Joseph Black and first isolated by Sir Humphrey Davy in 1808. Widely used for aerospace, industrial and medical appliions, magnesium is often alloyed with aluminum to create a strong, lightweight, and corrosion resistant alloy
Abstract A strongly textured sheet of magnesium alloy AZ31 has been subjected to tensile testing at temperatures between aient and 300 °C. Structures have been examined by optical and transmission electron microscopy and also by atomic force microscopy to quantify surface displacements seen at grain boundaries. Plastic anisotropy varies strongly with test temperature as was observed
Making composites out of these magnesium alloys by reinforcing them with ceramic particles or fibres appears to be a viable alternative for improving their thermal stability. The work reported here involved experimental studies on the tensile behaviour of AM100 magnesium alloy and its composites at different temperatures.
Aug 06, 2013· Magnesium alloys are some of lightest structural materials around. Magnesium AZ91D cast alloy is a high-purity alloy that has excellent corrosion resistance, excellent castablilty and good strength. It is the most commonly used magnesium die casting alloy. The following sections will discuss magnesium AZ91D cast alloy in further detail.
Tensile bars, obtained from the Institute of Magnesium Technology in Quebec, Canada, were cast AM60B magnesium alloy containing approximately 6% aluminum and 0.15% manganese by weight. The samples were cast using a cold chaer die casting machine with a 600-ton locking force and an injection temperature between 675 and 690 degrees Celsius.
The deformation and failure behavior of an AM60 magnesium alloy was investigated using tensile test on circumferentially notched specimens with different notch radii. The strain and stress triaxiality corresponding to the failure point were evaluated using both analytical and finite element analyses. Coining with systematical observations of the fracture surfaces, it is concluded that
Nov 17, 2017· Sumitomo Electric Industries, Ltd. has developed jointly with the University of Toyama a high heat-resistant magnesium alloy for die casting* 1 appliions. The automotive industry is presently required to conserve the environment by reducing CO 2 emissions of vehicles. A promising way of meeting the above requirement is to improve the fuel efficiency of vehicles by reducing their weight.
